Abstract
An analytical method was developed for the determination of tetrabromobisphenol A (TBBP-A), major brominated flame retardant, in water sample by liquid-chromatography/mass spectrometry (LC/MS) . After collecting TBBP-A in water into a solid phase extraction cartridge, it was extracted into acetone. The sample exract in which13C12-TBBP-A was spiked as an internal standard was concentrated and redissolved into methanol, and it was subsequently determined by LC/MS. Sufficient amount of [M-H] -ion was formed in negative mode of the atmospheric pressure chemical ionization (APCI) and it was used for the selected ion monitoring (SIM) in LC/MS. The recovery, relative standard deviation (RSD) and limit of detection (LOD) were 90.5%, 7.2% (n=5) and 0.1ng/l, respectively. TBBP-A was detected in leachate samples in the range from n.d. (i.e. not detected) to 43ng/l . On the other hand, it was not detected in river water samples. TBBP-A in leachate may be an indicator that can screen landfill sites where waste flame retardant plastics were deposited.
